FYI, Around the database you will often see us describe the condition of units on a scale of 1-10. #10 would mean the product is new from one of our suppliers, such as Behringer, Audio Technica, etc. #9 means the product is in perfect condition but is used, #8 implies there are some minor cosmetic scratches but unit is mechanically perfect, and so on and so forth.
